Detailed Description
In order to make the technical means, the creation features, the achievement purposes and the effects of the utility model easy to understand, the utility model is further explained below by combining the specific figures. The terms "upper, lower, left, right" and the like in the present invention are not intended to limit the technical solution specifically, but are described only for the convenience of understanding according to the orientation shown in the drawings of the specification.
In a first aspect of the present invention, a prefabricated heat-insulating pipe installation structure, as shown in fig. 1-2, includes a C-shaped chute 1 and at least one pair of pipe clamps 2, wherein both free ends of the C-shaped chute 1 extend inward to form a blocking portion 11; two notches 21 capable of accommodating the blocking part 11 are symmetrically arranged on two sides of the lower part of the pipe clamp 2; the middle parts of the same pair of pipe clamps 2 can be matched to clamp the prefabricated heat-insulating pipe 3; the upper part of the pipe clamp 2 is provided with a connecting hole 23. The two coupling holes 23 of the same pair of pipe clamps 2 may be coupled by a fastening means.
The installation structure can be used in a place with a bridge frame, namely the C-shaped sliding groove can be horizontally arranged on the bridge frame (the opening of the C-shaped sliding groove faces towards the unlimited part, preferably upwards or towards the side surface), the length of the C-shaped sliding groove is unlimited, and all parallel prefabricated heat insulation pipes can be installed. The fastening means may be a bolt, that is, the two coupling holes of the pair of pipe clamps may be coupled by a bolt. The blocking part is used for supporting the prefabricated heat-insulating pipe placed on the pipe clamp and blocking the pipe clamp from falling off the sliding chute. The pair of pipe clamps corresponds to one prefabricated heat-insulating pipe, and a plurality of corresponding pairs of pipe clamps are required to be arranged on occasions with a plurality of prefabricated heat-insulating pipes.
When the prefabricated heat-insulating pipe is installed, the prefabricated heat-insulating pipe can be placed at a proper position on the C-shaped sliding groove, then a pair of pipe clamps are placed into the C-shaped sliding groove from two sides of the prefabricated heat-insulating pipe, and the blocking part enters the notch (or the pipe clamps can be placed firstly and then the prefabricated heat-insulating pipe is placed between the pair of pipe clamps, so that the effect is the same); and clamping the prefabricated heat-insulating pipe by using the pair of pipe clamps, penetrating a bolt into a connecting hole of the pair of pipe clamps, sleeving a nut and screwing.
In the embodiment, the prefabricated heat-insulating pipes are separated and neatly installed on the bridge frame by the C-shaped sliding grooves and the pipe clamps, compared with a traditional installation structure, the prefabricated heat-insulating pipes are lower in cost and simple to install, and contact and friction among different prefabricated heat-insulating pipes can be effectively avoided.
In one embodiment, as shown in fig. 1-2, a connecting section 24 is provided between the upper portion and the middle portion of the pipe clamp 2, and the connecting section 24 and the upper portion and the middle portion are both obtuse angles. In particular, the connecting section is at an equal angle to the upper and middle portions, with the upper and middle portions of the clamp parallel.
The connecting section with the obtuse angle connection is arranged between the upper part and the middle part of the pipe clamp, so that the round prefabricated heat-insulating pipe can be clamped and fixed better, and the sliding displacement between the prefabricated heat-insulating pipe and the pipe clamp is effectively prevented.
In one embodiment, as shown in fig. 2, the end of the blocking portion 11 is an inwardly bent hook-shaped structure, the height of the hook-shaped structure is less than the width of the notch 21, and the lower edge of the notch 21 is provided with a protrusion 211 extending upwards.
The height of the hook-shaped structure is smaller than the width of the notch, so that the upper height and the lower height of the pipe clamp can be adjusted in a limited way to be suitable for fixing prefabricated heat-insulating pipes with different diameters. The combination of the hook-shaped structure and the protrusions can enable the opening of the C-shaped sliding groove to be more stably connected with the pipe clamp when placed towards the side face.
In a second aspect of the present invention, a prefabricated heat-insulating pipe installation structure, as shown in fig. 3, comprises a block 4 and a tightening device 5, wherein the left and right sides of the middle part of the block 4 comprise two symmetrical concave arc edges 41 for matching with the prefabricated heat-insulating pipe, the upper part of the block 4 is provided with an upper through hole 42 for communicating the left and right sides, and the lower part is provided with a lower through hole 43 for communicating the left and right sides; the tightening means 5 can penetrate through the upper and lower through holes 42 and 43 to tighten the prefabricated heat-insulating pipe 3.
Wherein the tightening means may have a band-like or rope-like structure as long as it can be used to tighten the prefabricated heat-insulating pipe. The concave arc-shaped sides refer to the left and right sides of the surface and not only the edges. The concave arc-shaped edge can enable the stop block to be in closer contact with the prefabricated heat-insulating pipe, and the mounting position of the prefabricated heat-insulating pipe can be more stable. The mounting structure can be used in places without bridges, and can fix a plurality of prefabricated heat-insulating pipes together after being arranged in order.
When the prefabricated heat-insulating pipes are installed, the stoppers are placed between two prefabricated heat-insulating pipes, then the fastening devices are used for penetrating the stoppers from the upper/lower through holes, bypassing the prefabricated heat-insulating pipes along the outer sides of the prefabricated heat-insulating pipes and penetrating the stoppers again from the lower/upper through holes, and then the fastening operations are performed on the prefabricated heat-insulating pipes after bypassing the outer sides of the other prefabricated heat-insulating pipes. The number of the prefabricated thermal insulation piping to be installed herein may be plural, and accordingly, a stopper is disposed between each pair of the plural prefabricated thermal insulation piping, and the fastening means is continuously passed through the plural stoppers and bypassed outside of the prefabricated thermal insulation piping at both ends.

In one embodiment, as shown in fig. 3, the inside of the block 4 is a hollow structure, and the upper through hole 42 is communicated with the lower through hole 43.
Wherein, if the dog adopts hollow shell structure, through-hole and lower through-hole intercommunication on the dog promptly, then the device of tightening can also cross to pass the dog and tighten prefabricated adiabatic pipe according to "∞" mode. For example, the fastening device may be inserted into the block from the left side of the upper through hole and then inserted out from the right side of the lower through hole, or inserted into the block from the left side of the lower through hole and then inserted out from the right side of the upper through hole.
